For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Transdermal fentanyl provides continuous opioid exposure that depresses respiration, and pancuronium paralyzes respiratory muscles. In ventilated patients this is manageable, but postoperative hypoventilation is a concern.
What this interaction means in plain words
Fentanyl transdermal and Pancuronium can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Central opioid respiratory depression adds to neuromuscular blockade of respiratory muscles.
What to do
Account for the patch's ongoing opioid effect when dosing anesthetics and analgesics. Ensure ventilatory support and monitor respiration until full neuromuscular recovery.
What to ask your pharmacist

- Does the dose of either medicine need to change?
